K2-290A’s two close-in planets’ orbits are retrograde relative to the star’s rotation. Today’s paper explores how dynamical interactions in the triple star system may have caused this misalignment.
There are still a lot of unknowns when it comes to extrasolar planet formation. Today’s authors take a look at a group of known terrestrial exoplanets to see if they can find a correlation between the planets’ compositions and the chemical abundances of their host stars.
We report on Days 4 and 5 of the virtual events based around the cancelled winter AAS meeting.
How common are icy polar caps like ours on Earth-like exoplanets? Today’s paper explores the many versions of surface ice possible on Earth-like exoplanets, even including equatorial ice belts!
Astronomers find free-floating planets and where they came from.
Astronomers around the world are excited about the launch of a new telescope! In today’s bite, read about what that might bring for detections of biosignatures in the atmospheres of exoplanets.
